The Car Connection's Take
TCC Rating
8.6
8.4
TCC’s Bottom Line
Elegant, stylish, comfortable, and quick, the 2012 BMW 6-Series is one of the top choices for a grand-touring coupe or convertible--as long as your budget can handle it. A powerful near-exotic luxury convertible, or a grand tourer with German precision? The 2012 Mercedes-Benz SL Class is both.
